Problem: The battery pack cannot be fully charged by the power-off method in the standard charge time for your compute
Solution: The battery pack might be over-discharged. Do the following:

- Turn off the computer.
- Make sure that the over-discharged battery pack is in the computer.
- Connect the AC adapter to the computer and let it charge.
- If the optional Quick Charger is available, use it to charge the over-discharged battery pack.
- If the battery pack cannot be fully charged in 24 hours, use a new battery pack.

Problem: The operating time for a fully charged battery pack is short.
Solution: Discharge and recharge the battery pack. If your battery's operating time is still short, use a new battery pack.

Problem: The computer does not operate with a fully charged battery pack.
Solution: The surge protector in the battery pack might be active. Turn off the computer for one minute to reset the protector; then turn on the computer again.

Problem: The battery pack cannot be charged.
Solution: You cannot charge the battery when it is too hot. If the battery feels hot, remove it from the computer and allow it to cool to room temperature. After it cools, reinstall it and recharge the battery. If it still cannot be charged, have it serviced

Capacity is the length of time you can run your system on a fully charged battery. It is normal for all batteries to lose some capacity over time. Each time you discharge and recharge your battery, you will lose a very small amount of this capacity.

You may also want to check for specific information on your system; for example, some BIOS updates include power management enhancements. Other systems have specific tools to help with battery life. To find drivers and files for your system, go to ThinkPad software and device drive file matrix and select the link for your system.

The battery will lose capacity when left in a system without the AC power attached because the system will draw a small amount of current that will deplete the capacity over time. Batteries will lose some charge over time due to self discharge; this is normal.

System shuts down before, or operates after battery status indicator shows empty

When the actual battery capacity is different from the displayed capacity, the above symptoms can occur. To reset the displayed capacity so it matches the actual capacity, discharge the battery to 10% or below and recharge the batteryto at least 96%.

Verify system runs on AC power. If so, check battery health in Power Manager as outlined above. If system does not run on AC power, remove battery (if system has removable battery) and retest. If system works, contact support to replace battery. If system still does not operate, contact support.
